Title: Magnetic disk device
Inventor: ASADA HIDEO
IPC: G11B25/04
Filed: 1986-03-31
Abstract: PURPOSE:To increase the hygroscopic effect of the air of the inner part of a disk enclosure and to cope with even an abrupt humidity variation by providing a vent hole communicating the high air pressure spot and low pressure spot caused by an atmospheric pressure difference generating means and the container storing a moisture absorbent in the inner part. CONSTITUTION:A disk enclosure incorporates the container 5 having a vent hole at the high and low spots of the air pressure of the air stream caused by the rotation of a magnetic disk and having a moisture absorbent in the inner part. With the rotation of the magnetic disk 2, the air pressure at the center of the rotation is reduced, so the air stream 4 flowing toward outside from the center of the magnetic disk 2 is caused in the air of the inner part of the disk enclosure 1. The container 5 storing a moisture absorbent has vent holes 6a, 6b, which communicates to the center of a magnetic disk rotating mechanism 3 by a duct 7. An air pressure difference is thus caused on the vent holes 6a, 6b. The inside air of the disk enclosure 1 becomes passing through the container 5 storing the moisture absorbent and the air moisture is absorbed by the moisture absorbent.

Title: Piezoelectric sensor
Inventor: TOYODA HIDEKI
IPC: G01L9/08
Filed: 1993-03-09
Abstract: PURPOSE:To improve heat resistance and to achieve high accuracy in pressure measurement without providing a cooling means by using a piezoelectric element comprising a single crystal of lithium tantalate, whose changing rate of the output with respect to temperature is approximately zero. CONSTITUTION:A main-body metal fitting 1 is screwed into a sensor-attaching hole, which is provided at the cylinder head of an internal combustion engine. A detecting element comprising a piezoelectric element 11, a pressure transfer rod 9 and the like is contained in the inside of the main-body metal fitting 1. A diaphragms 6 is placed for a seal to the lower edge. The internal pressure in the cylinder is propagated into the piezoelectric element 11 through the diaphragm 6 and the pressure transfer rod 9. The electric signal, which is proportional to the inner pressure is taken out, and the inner pressure is detected. At this time, the piezoelectric element 11 is exposed to high combustion temperature and cannot be used because of the deterioration of the piezoelectric characteristic unless a cooling means is not used. When the piezoelectric element 11 is constituted by using the single-crystal piezoelectric material of lithium tantalate, however, there is almost no temperature dependency, and the highly accurate pressure measurement can be performed without a cooling device. Especially, pyroelectricity is not generated in the piezoelectric element 11, which does not contain a Z component in the polarizing direction.
